Abstract (en)
A robotic mower sensor assembly (119) for detecting a boundary wire signal. The sensor assembly (119) includes a plurality of analog inductive sensors with a first inductive sensor (120) oriented along a first axis (Z) and a second inductive sensor (122) oriented along a second, different axis (X). Each inductive sensor (120, 122, 124) is configured to generate a signal indicative of the distance of the robotic mower (100) from the boundary wire (103, 104). A control unit (101) communicating with the sensor assembly (119) is configured to operate the robotic mower (100) in response to the signals from the sensor assembly (119) which are indicative of the distance of the robotic mower (100) from the boundary wire (103, 104).
